The new LT2 engine is a 6.2-liter V8 making 495 hp and 470 lb-ft. The bigger change is what it's connected to -- an eight-speed, dual-clutch transmission from Tremec. When it comes to performance there's no doubt DCTs are quicker. How quick? The new C8 will have a 0-60 mph time of less than 3 seconds.
